Host
Add the following lines to /etc/rc.conf:
nfs_server_enable="YES"
mountd_enable="YES"
mountd_flags="-n"
rpc_lockd_enable="YES"
rpc_statd_enable="YES"
rpcbind_enable="YES"
For some reason the NFS server needs to be restarted the first time after boot. A simple way to do this automatically is:
# echo "service nfsd restart" >> /etc/rc.local
Set the sharenfs property to the dataset you want to share. Replace the IPs
and pool/dataset* with your desired values. ZFS properties are documented in
zfsprops(8).
We’re going to share 2 datasets, one with read-write and one with read-only access:
# chmod -R 777 /pool/dataset_rw
# zfs set sharenfs='-network=192.168.1.0/24,-alldirs' pool/dataset_rw
# zfs set sharenfs='ro=192.168.1.0/24,-alldirs' pool/dataset_ro
Start the NFS server:
# service nfsd start
# service mountd reload
If any sharenfs changes occur while mountd(8) is running, it has to be
reloaded again.
Guest
Acquire the host’s IP address using ifconfig(8) on it first. We’ll assume it’s 192.168.1.5.
Mount the filesystems. /pool/dataset* corresponds to the actual mount point
of the dataset in the host:
# mkdir -p /mnt/dataset_rw /mnt/dataset_ro
# mount -t nfs -o rw 192.168.1.5:/pool/dataset_rw /mnt/dataset_rw
# mount -t nfs -o ro 192.168.1.5:/pool/dataset_ro /mnt/dataset_ro
When done, unmount:
# umount /mnt/dataset_rw /mnt/dataset_ro
In case you want the filesystems to be mounted on boot, add the following lines
to /etc/fstab:
192.168.1.5:/dataset_rw /mnt/dataset_rw nfs rw 0 0
192.168.1.5:/dataset_ro /mnt/dataset_ro nfs ro 0 0
